Once the hunting grounds of the city's elite, the wider Tiergarten area extends all the way to the Brandenburg Gate and includes the Reichstag. With a name that literally means "Animal Garden" (apt as it contains the city's zoo), Tiergarten is Berlin's largest inner-city expanse of greenery - an urban lung, as it were. Once part of West Berlin, today, Tiergarten is also an administrative district, but contains Tiergarten event venues that host the city's mega-concerts and the start of the Berlin Marathon.
Approximately five miles north of Tiergarten, Berlin Tegel "Otto Lilienthal" Airport (TXL) is the main international entry point for the city, that is until the new Berlin Brandenburg Willy Brandt Airport (BER) opens in 2015. Flights arrive from all over the world.
There are no large convention venues in Tiergarten; Berlin's main convention center is the Berlin ExpoCenter City, which has 1.6 million square feet of exhibition space in 26 exhibit halls, as well as 54 meeting rooms and a 100,000-square-foot Summer Garden, In Charlottenburg is Europe's largest congress center, the International Congress Center Berlin, which has 80 rooms seating between 20 and 9,100 persons. Opening in early 2014 – operated, as are both the above facilities, by Messe Berlin – is the CityCube Berlin, which will have 120,000 square feet of exhibit space, eight conference halls for between 400 and 3,000 persons, a column-free space for up to 5,000 persons and 37 meeting rooms.
Hotel venues in Tiergarten include the 701-room Hotel Berlin, Berlin, which can host receptions of up to 1,200 persons; the 505-room Maritim Berlin, which has the ability to host 5,500 persons in 49 different rooms; the world-famous, 382-room Hotel Adlon Kempinski Berlin, which has 14 meeting rooms and two ballrooms able to host 450 and 500 persons, respectively; and the 267-room Hotel Berlin Concorde, which has new, 81-room Das Stue, which means "living room" in Danish and is a boutique property with meeting space.
This unique area has numerous special event venues to match. Choose between E4 Berlin, a circular, modernist structure consisting of three floors covering 10,000 square feet on the Potsdamer Platz and with space for up to 1,200 guests; Loewe Saal lounge, which is on the second floor of the listed Ludwig Loewe-Yard building, with space for 1,000 persons and the Berliner Lounge for 80; Tipi am Kanzleramt, a huge tent structure in the middle of the park itself that has space for receptions of up to 600 persons; Berlin Zoological Garden, which contains the Zoo-Aquarium and has function space amid coral reefs and piranhas for up to 300 persons; and modernist Deutsche Kinemathek, which has the 2,000-square-foot Event Room in its Filmhaus section that can accommodate 350 guests for receptions - more if the atrium is included.
Great restaurants in Tiergarten for large parties include Facil, with nouvelle-German cuisine; Vox, for gourmet dining with a private dining room; Cafe am Neuen See, in the park itself and overlooking a lake; Teehaus Tiergarten, a teahouse with a light menu that also is in the park; and even an Australian restaurant, Corroboree.
